"Don't worry, Xplane is just a loader to me, the SDK always comes first." -- Sandy Barbour
The X-Plane Plugin SDK allows third party programmers to create plugins for X-Plane. Plugins are programs written in C or another binary-compatible language.
Please note: the X-Plane Plugin SDK is for programmers; if you are not a programmer this site probably doesn't contain much useful information. You can read a non-technical explanation of plugins here.
